Roll the Dice

Now it's time to generate your own passphrase using real dice. As we mentioned in the Seed Phrase Guide, using casino-grade dice ensures the highest level of randomness (entropy). However, if you want to save money, any standard six-sided dice will work just fine. Even if your dice have slight imperfections, rolling multiple dice at a time will still provide sufficient randomness for a secure passphrase.

For this method, five dice are enough to generate each word.

Before rolling the dice remember that:

• Each word is generated by rolling one die five times or five dice once, providing 12.9 bits of entropy per word.
• A six-word passphrase gives 77 bits of entropy, which is strong security.
• For even stronger security, consider seven or eight words (90.3 or 103.2 bits of entropy, respectively).

How to Generate Your Passphrase

• Roll five dice at once.
• Record the five-digit number they form (e.g., 52465).
• Look up the matching word in the EFF Long Word List (e.g., 52465 = running).
• Repeat this process until you have at least six words for a secure passphrase.

Your final numbers might look like this:

52465 16663 55321 66621 22166 23234

Which translates to your final passphrase:

running cope snowfield yippee darling diaphragm

Your passphrase is now ready to use!
